Telkom *****ulent deduction

My contract was ending early December and I took a new one in end of November. I was advised that November will be the last time the old contract was going to deduct but now in February R80 is deducted from my account that I have no knowledge of and they have handed my account over because I disputed the R80. I reversed the amount from my account because I don’t know what it is for and it deducted on the 13th and I was misled by the consultant that November was going to be the last time the old contract was going to deduct. I called in their call centre and I was told only the new contract shows on the system, the R80 is seriously confusing me. They must remove my details from the handover company because this is *****ulent they have no business in handing me over, ruining my name.
